Stainless Steel is ideal for brewing at home on account of its toughness. More cost-effective options can be purchased at homebrew supply stores, yet be careful with "sticker shock" when selecting your equipment. On the other hand, stainless steel components should keep going forever, so it helps ensure that the brew day goes smoothly.
Another benefit of stainless steel is that a skilled welder can join fittings to the pot, allowing for valves and fittings to be connected. There are as many breweries configurations as their brewers; homebrewers can get serious about their hardware!
Regardless of whether you are looking for starting all-in-one pieces of equipment or looking to add a mash tun, lauter tun, boiling kettle or hot liquor tank, there are sure to be suitable options for starting and expanding your home brewery.
